About Sourced Prep

Sourced Prep makes study guides for licensing and certification exams, built on one rule: you should be able to check the answers. In the licensing guides, each practice question comes with a short explanation and a label naming its source, from a section of the statute or regulation to standard policy practice, and every statute and regulation cited is free to read online. The guides are written from the published content outlines or the primary rules, checked against the primary text in a separate review pass, and dated inside, so you know how current they are. When a rule changes or a reader reports an error, the correction is posted at sourcedprep.com. Sourced Prep is independent: not affiliated with or endorsed by any examining or licensing body, and no study guide can guarantee a result.

Each book states on its copyright page the month it was verified. Read any correction below together with that date.

Every report is checked against the primary text, and a confirmed correction is posted on this page under its book.
